Do all Flat Earth Believers at least agree that Bendy Light is necessary for a Flat Earth to exist?
I'm taking this from another post I did earlier, but people never seem to get directly to the point. This time I don't want to hear comments about bad grammar, spelling mistakes or semantics. I just want people to either agree with me, or tell me why I'm wrong.
I'm not trying to disprove the Flat Earth hypothesis in this post, I just want to know if you can all agree on this point.
The assumptions
I'm going to assume these parameters for this test:
-The earth is flat.
-The sun travels in a circle above the equator, which has a perimeter of 40000km
-Morning and evening happen when the sun is 1/4 of a circle away from us.
-The sun is approximately 10000km away from us horizontally at those times.
-Light travels in a straight line and radiates equally in all directions from the sun.
Numbers
Horizontal distance of the sun: hDist = 10000km
Angle of the sun above the horizone: angle = arcsin(vDist/totalDist);
Total Distance between the sun and the observer: totalDist = sqrt(hDist*hDist+vDist*vDist)
By this equation, we can assume that these values are correct:
vDist = 174.55065
totalDist = 10001.52328
angle = 1º
Conclusion
In order for the sun to appear 1º above the horizon in the morning, the sun must be 174.55065 km above the Earth at all moments. And remember that this still doesn't account for the sun setting behind the horizon.
There's a big problem with this distance: Between morning and noon, the sun has changed its distance to us by 9826.97km. This would have had an extremely noticeable effect on the size observed, which I don't know how to calculate at the moment. And don't tell me that you can't observe the sun's size. Have you ever tried using smoked glass, or the black area of an X-Ray photo?
QUESTION:
¿Do you still believe that this earth could possibly be flat without the existence of Bendy Light?
If not: Why?
